Original application filed May 29, 1919, Serial No. 300,702. Divided and this application led January 20, 1920. Serial No. 352,750.

To all w 7mm t may concern:

Be it known that I, Lnwis E. MORRISON, a citizen of the United States, and resident of hlewark, in the county of Essex and State of New Jersey, have invented certain'new and useful Improvements in Transfer Mechanisms for Printing Machines, of which the following is a specification.

This invention relates to transfer mechanisms of the type used in automatic printing machines for transferring the sheet tol transfer table the sheet is delivered or fed onto the platen, where it is seized and held by the well known gripping devices while being printed. The gripping devices are not illustrated, nor described herein, the same not being a part of this invention. The transfer table is mounted between the feed table and the platen and is provided with means for guiding and supporting the paper operating means for said table and also included in the disclosure herein.

It is the object of this invention to provide a transfer mechanism peculiarly well adapted for use with the printing ma hine referred to above. Another object is to provide a transfer mechanism of simple and practical construction and design, comprising comparatively few parts and requiring only slight and infrequent adjustments. (J'ther objects will appear as this specification proceeds.

Accordingly, my invention is embodied in a 'transfer mechanism constructedv and arranged as hereinafter set forth and as illustrated in the accompanying drawings, in which-- Figure 1 is a side View of a portion of a printing machine in which. the transfer mechanism forms a part; and

Fig. 2 is a perspective view of the transfer mechanism and adjacent parts;

Fig. 3 is a detail view in elevation of parts of the transfer mechanism;

Fig. a is a plan view of said details shown in Fig. l. I

As set forth in the pending application referred to, the automatic printing mechanism therein disclosed is especially Wiehl, adapted for use with job presses of the well known Chandler and Price construction and the printing press disclosed herein is a Chandler and Price press. I wish it, however, distinctly understood, that I have no intention of limiting my invention to any particular press. As the general main elements of j ob printing presses are rwell known in the art, it requires but brief reference and outline illustrations thereof for the purpose of understanding this invention. In the drawings therefore, the reference numeral 3 denotes the main frame of the press to which the platen 6 is pivoted at 5, while 7 denotes the form member. The disk 12 in Fig. 2 represents the platen locking cam of which the cam surface is not shown, but only the outer circular disk is illustrated.

It will be understood that Vas usual the platen is operated from the printing position shown in full lines in Fig. 1 to the open position shown in dotted lines when it receives the paper to be printed, and that likewise the form member 7 is operated from the printing position shown to the open position, not shown herein, but fully disclosed in my said pending application.

On the left side of the press, shown in Fig. 2, there vis secured to the frame a bracket 15 having a rearwardly inclined upright 16 and a depending portion 17. Similarly, on the right side of the press, there is provided a bracket 18 having similar portions16 and 17, Fig, 1. The bracket 18 also has a forwardly inclined upright 19 and a cam support 20. The paper feed table 24 is pivoted horizontally. at 25to the support 22 and rests normally on the said two uprights 16, 16, which are provided with receiving shoulders Q6, 26. -The feed table is further adapted to be raised on the pivot 21 into a horizontal position shown in dotted lines and may thereaftei` be svmng laterally 18. parte are in the normal position as shownA vin Fig. l where it will be observed that the as disclosed more fully in the pending plication referred to.

lThe.- feed table and the bearing support 22 are swung vertically as one piece by the following means, see Fig. 1. 28 is a curved lever pivoted at 29 to the bearing` 22 and having a tail stop 30. 31 is a link pivoted at 32-to the lever 29 and at38 to the bracket 34 is a stop pin in the lever 81. rlhe lcver 28l rests against the stop pin and thepivot 32 is below the level of the pivots 29 and 33 so that there is a deadlock as will be understood. When itis desired to raise the feed table, the lever 28 is pulled forward and downward into the dotted position shown, whereby the bracket 22 is -moved rearward as shown and the feed table lifted off the upright-s 16, 16, and into horizontal position as indicated. Then the lever V28 is moved into its lowermost position, the tail stop '30 abuts the stop pin'a on the under side thereof, and Vthe pivot 29 now comes between the pivots and 35S-,and is deadlocked as indica-ted.l Thereafter the feed table may be swung horizontally to the 4right and a hand feed board not shown, may

be -placed inaV socket 37 and the press may then behandfed and handdelivered. By movements in the `opposite direction. the feed table is brought back laterally over the frame andis then lowered to rest on 'the brackets 15 and 18 on the parts 16. 16 thereof.

On top of the feed table rests the paper board 40, which comprises the board 40 supported in an inclined position by meansv of its sides or legs 41, 41;

The topfsheetis separated fromthe pile of sheets 52 and fed to the transfer mechamsm and the platen by a nozzle 53 support- 'ed o n a rod 54 kcarried by an' arm 56 which 1s pivoted to and moves with the Vform 7 by means not shown (but disclosed in the said pending application). The two eX- treme positions of the nozzle 53 andthe arm 5,6, are, however, illustrated in Fig. 1 herein. The nozzle arm carries a roller 78 which 'runs on the cam 79 secured to the cam support 20- aforesaid and whereby thevnozzle is guided in its movements as is'obvious. It is further understood that suction is' applied to the nozzle 53 when it is moved down upon thepaper l52 so as to pickup thetop sheet'shown m full lines and that the suction is cut olf when the paper is released land `dropped on the transfer table, at the and a lower shaftlljournaled'in said'side arms. The shaft 8a is constantly rotated by means of the metal roller 185 fast on `it and liber roll ers" 86 and 8T. The latter is driven from the wheel V88 on a shaft or stud 89 which also carries `a smaller wheel 90, which Vis driven from the platen locking cam 12.

the plate96 which is slotted at 97 and which I plate is adapted to swing on theshaft 8a. 98 is a spring which bears againsta stud 99 fast in the arm 88. Thus the wheel. 87 is kept down upon the wheel 88 by the spring' 98 and the wheel 86 rests by gravity on wheel 8S and roller 85, whereby good frictional driving is obtained.

Referring new `to Fig. 1, it will be seen that the arm 833 on the right side of the press carries acam or stop 100 pivoted on said arm at 101 and adjustablev by a screw 102 and slot 103. The said arm 83 also carries Va lip 10st adapted torest upon aroller 105 carried byV an arm 106 pivoted to theplaten at 10T and connected to the Vupright 16 of the bracket 18 by a link 108.

rllhe transfer Atable further is provided with paper supports 108. and side guides 109. The latter carry lingers 110. The whole transfer table may be swung upward and forwardV until it restsv upon the feed table as shown in Fig. 1. This is done to get the transfer table out of the way when it is desired to examine the platen and when the feed-table is raised and -moved to one side as explained inthe foregoing. the transfer table is lowered, it is brought to reist on the roller 105. When the press opens or closes, `the transfer table. isr lifted up'out of the way of the platen by the arm 106 and roller 105, saidarin 106 moving with the platen as shown in full and dot-ted lines.

VlVhen the transfer table isV lowered, the

spring 98 onthe plate 96, Figs. 3 and 4, forces the plate downward, hence the wheel V87 int-o driving contact with the wheel 88.

When the 'transfer table is raised the spring merely forces the plate 96 into a position with the end of the slot 9T. The wheel 86 will always fall into contact with the wheel 1When y 87 and roller 85 thus insuring a good drive 'l for the shaft 8a.

If a shrrgt sheet is fed, it is of course, desirable to have the transfer table lowered as much as possible so as to have the distance between the shaft 8a and the platen as small as possible and consequently the cam or stop table out of Contact with the lifting roller 105. Then a longer sheet is `fed, it is `desirable to increase the distance between the shaft Set and the platen and the cam 100 will in that case be adjusted so that when the transfer table is in its lowermost position, the said cam `100 will abut the edge of the transfer table and keep it the desired distance away from lthe platen and in that case, when the platen moves up, the roller 105 will simply be moved out of contact with the lip 104.

To sum up: The transfer table bridges between the feed table and the platen. The transfer table is moved up out of the way by the arm 106 and roller 105. lhen the transfer table moves down it will continue to rest on the roller 105 except in the case of long sheets, when the transfer table will not beA lowered on the roller 105, but the latter will move down away from the transfer table and the latter will only move as low as permitted by the cam 100. The sheet is dropped upon the transfer table and is run off onto the platen by the swiftly rotating shaft S4.

lt will be seen from the .foregoing that the transfer mechanism comprises comparatively few parts. That proper adjustments have been provided for by the supports 108 and side guides 83 as well as by the cam 100. Also it will be noted that when the table 24 has been swung upward and is again lowered on the cam roll 105, the table comes back onto a position where it will again operate in perfect synchronism with the platen and the press.

It is further understood that I do not desire or intend to limit my invention to the exact disclosure herein, but that changes may be made without departing from the spirit of the invention and the scope of the appended claims.
